💡 Tips for a Successful Server Setup
-
Minimum Install: Always start with a "Minimal" or "Net-install" to reduce the attack surface.
-
Separate Partitions: Keep
/home,/var, and/on separate partitions to prevent log files from crashing the OS. -
SSH Keys Only: Disable password authentication immediately in
/etc/ssh/sshd_config. -
Documentation: Always maintain a digital "Runbook" of every custom configuration change made to the server.
